Title: Composite type coupling circuit
Inventor: OBUKA TERUTAKA
IPC: H01P5/08
Filed: 1988-06-15
Abstract: PURPOSE:To fetch only a signal which is a purpose by providing a coupling circuit main body with being coupled to a frequency selecting circuit and obtaining a coupling output. CONSTITUTION:A conductor filter 21 is a filter, for which a Tg/4 length resonator is used. An input signal to this conductor filter 21 is outputted by electric field coupling between an input terminal 22 and an output terminal 23, however, the output to a coupling circuit main body 24 side can be executed by loop coupling due to magnetic field coupling. The said coupling circuit main body 24 can adjust coupling quantity by adjusting the area of a loop. Thus, by impressing a detected signal from the input terminal 22, a signal, for which a spurious wave to be limited to a necessary frequency band is removed in the conductor filter 21, can be outputted from the coupling circuit main body 24.

IPC: G01R29/08
Filed: 1991-06-18
Abstract: PURPOSE:To facilitate the measurement and adjustment of a phase difference while achieving a reduction in cost by eliminating the need for making a cable for connection accurately. CONSTITUTION:In a phase difference measuring method, a reception level of a synthetic radio wave having a known phase radiated from transmitting antennas 1 and 2 is measured with a measuring device 5 beforehand and the reception level measured is compared with that of a radio wave having a phase difference unknown to measure a phase difference. In a phase difference adjusting method, a cable for opposite phase is inserted in a length equivalent to a half of the wavelength of input radio waves to be radiated from antennas 1 and 2 into one of cables 3 and 4 for connection to connect a wireless device and the antennas 1 and 2 and a cable for adjustment is inserted properly in a length less than the half wavelength of the input radio waves into either of the two cables 3 and 4 for connection to adjust the receiving level to the lowest. Then, the phase difference is adjusted by removing the cable for opposite phase.

Abstract: PURPOSE:To securely return lubricant oil into an oil sump during a normal operation while restrain the reverse flow of the lubricant oil by a foaming phenomenon at the start of an operation by forming a spiral groove at a surface opposed to at least one of a press plate and a shaft disposed in a penetrating portion. CONSTITUTION:After lubricating each bearing during a normal operation, a force in an advance direction of a screw is exerted on lubricant oil dropped on a press plate 30 by the rotation of a shaft 9, that is, the rotation of a spiral groove 32a disposed in an oil cap 26 so that the lubricant oil is securely returned into a lower oil sump 25. At the start of an operation of a compressor, a refrigerant melted in the lubricant oil or the like is abruptly foamed so as to flow out together with the lubricant oil above the press plate 30 from the oil sump 25 through a space formed between the press plate 30 and the oil cap 26. However, the spiral groove 32a on the oil cap 26 is rotated by the rotation of the shaft 9 so that the force in the advance direction is applied to the lubricant oil in the space. Therefore, the lubricant oil is returned to the oil sump 25 to be restrained from flowing reversely by a so-called foaming phenomenon.

CONSTITUTION:Upon operating the pump, the sealing water is supplied by the hydraulic pressure higher than the internal pressure of the pump and the slide ring 11 is pushed toward the inside of the pump by said hydraulic pressure so as to have a normal shaft sealing function. Upon stopping the pump, the sealing water is not supplied, therefore, the slide ring 11 is pushed toward the outside of the pump, which is contrary to the case upon operating, by the hydraulic pressure in the pump, the ring is contacted with the sealing surface of a sleeve 2, the shaft is sealed by the slide ring 11 and the sleeve 2 and the inside of the pump is interrupted from the outside thereof, therefore, the high temperature water in the pump will never leak to the outside thereof. Accordingly, supply of the sealing water upon stopping the pump becomes unnecessary and invasion of the sealing water into the pump may be prevented.

IPC: C10B39/02
Filed: 1982-08-24
Abstract: PURPOSE:To improve the volume efficiency, by moving a moving guide while moving a coke bucket in one direction to make a pile of the coke formed in the coke bucket flat in the running direction of the coke bucket. CONSTITUTION:A coke cake 2 after the completion of the carbonization is pushed by a pusher ram 3 from a coke oven 1 to a coke bucket 6. In the process, a moving guide 5 is reciprocated in the directions (X-X'), and the coke bucket 6 is moved in the direction (Y) at a suitable speed. The movements of the coke bucket 6 and the moving guide 5 are combined to receive a coke in the coke bucket 6 in an optional orbit. The moving guide 5 is moved while moving the coke bucket 6 in the direction (Y) to move the tip of the moving guide 5 in a wide range of the coke bucket 6. Thus, the pile formed in the coke bucket 6 is flat also in the running direction of the bucket 6, and the volume efficiency is improved.

Filed: 1986-06-25
Abstract: PURPOSE:To rapidly search an editing point by reversely rotating a motor when a speed set is altered from a high speed to a low speed to decelerate the speed, and releasing a brake when becoming a reference speed. CONSTITUTION:When the output of a shuttle speed generator 2 is altered from 5 times speed data to one times speed data, a capstan speed switching detector 12 detects it, and supplies its output signal to a brake circuit 11 and a signal selector 14. The brake circuit 11 switches the rotating direction of a capstan motor reversely, and the selector 14 selects the output of a brake voltage generator 15 to supply it to a capstan motor. When the rotating speed information of the motor becomes equal to the output of a reference speed information generator 13, a speed comparator 17 returns the rotating direction of the motor forward. Simultaneously, the selector 14 selects the output signal from a voltage amplifier 7.

Filed: 1993-06-18
Abstract: PURPOSE:To improve the operability for both input of handwritten characters and editing of documents by securing the characters when the writing of them is started for input of the recognition results of these handwritten characters. CONSTITUTION:The changing state is shown at the left side of a diagram for the part near the input position of a character in a next display editing area 103, and the state where the character is written by the hand of an operator in a character input frame 101 is shown at the right side of the diagram. The 1st stage shows a state set before a user starts the input of characters. At the 2nd stage, a substitute mark is put into a position of a document where the recognizing result of a character is inserted, i.e., the left side of a cursor 103 after the user starts to write the character. Therefore a place where the character recognizing result is inserted is already secured when the user has written the character as shown at the 3rd stage. Thus the user can starts a document editing operation at an optional time point without confirming whether the recognizing result is secured or not.
